Abstract:By using the parallel observation data of photoelectric digital sunshine recorder and dark-tube sunshine recorder of national meteorological station in Beijing from January to June in 2019,based on the principle of two kinds of sunshine recorder,this paper compares and evaluates the sunshine recorders through the absolute deviation,relative deviation,monthly extreme value test,data consistency and other parameters.According to the evaluation results,the differences of observation equipment are analyzed.The advantages and disadvantages of two kinds of sunshine recorder observation processes are summarized to provide reference for realizing the accuracy of automatic observation data.
